I tried to bid a name on ENS but it says
"no accounts added to dapp"
I have metamask google extension linked to myetherwallet.
Please let me know how to add an account on dapp.
then click import account
Now you have 2 choices via the dropdown either
A input your private key
B add the json file (you may wish to have a relatively small amount of ETH in this account from a security perspective)
Alternatively you could generate an address from within Metamask and send a few ETH to it but that may be O/T I suppose...
